Netstor NA211TB: Additional PCIe slots for Mac computers via Thunderbolt 3


With the NA211TB3 expansion chassis, Mac users can use additional PCIe cards when all slots are already occupied.Via the Thunderbolt 3-Port - the cable version of the incredibly fast PCIe bus - the services of the plug-in cards implanted in the NA211TB3 can be used on the host computer. Since this does not affect the performance, it creates a very powerful external solution.

The user can install three up to 315 mm long and 120 mm high PCIe cards according to version 3.0 x8 in the enclosure - two slots are available for PCIe x16 cards. Compatible variants are available as graphic, audio or network cards and also as RAID controllers. (For example, RAID controllers from Areca, ATTO and Highpoint are supported.) Provided that the appropriate software is installed, this external solution expands the host computer with the special talents of the expansion cards.
